I have heard people stomping in my kitchen when I was the only one home. I would think "Why would a spirit or ghost want to bring attention to itself like that??"

There was also a good point in time where it felt like there was something standing over me while I would sleep. This was a while ago but I used to see what looked to be a black silhouette standing in the corner of my bedroom. Every 3 nights or so it would switch from corner to corner, or even at one point standing directly bedside me.
